 * 2010 M. Zumalacarregui et al, "Disformal Scalar Fields and the Dark Sector of the Universe" arXiv
 * The canonical scalar field Lagrangian, when coupled to a disformal metric, turns out to have relations to bimetric dark matter theories and to describe many specific dark energy models at various limits, thus providing a surprisingly simple parametrisation of a wide variety of models including tachyon, Chaplygin gas, K-essence and dilatonic ghost condensate.
 * 2012 C. van de Bruck, G. Sculthorpe "Modified Gravity and the Radiation Dominated Epoch" arXiv
 * In this paper we consider scalar-tensor theories, allowing for both conformal and disformal couplings to a fluid with a generic equation of state.

 * Such interactions are classified by their tensor structure into conformal (scalar), disformal (vector) and extended disformal (traceless tensor), as well as by the derivative order of the scalar field.
